STRUCT MAX77620_VARIANT(9)

💅 struct max77620_variant — Kernel API Manual energy ✨

Okay so bestie, picture this: this little struct is literally the ✨personality card✨ for a chip variant. Like, every Max77620 chip variant is a different main character and this struct is the group chat bio that tells the driver how to talk to it. Data specific to a chip variant, periodt. 🫶

It's from the Kernel API Manual, and we are so lucky to have it.

🌸 SYNOPSIS 🌸

Bestie, here's the whole fit. Copy it exactly, no cap:

struct max77620_variant {
    u8 reg_onoff_cnfg2;
    u8 reg_cnfg_glbl2;
    u8 reg_cnfg_glbl3;
    u8 wdtc_mask;
    u8 bit_wd_rst_wk;
    u8 cnfg_glbl2_cfg_bits;
 };

Six u8 fields. Small struct, huge responsibilities. Iconic. 👑

🎀 Members 🎀

These are the members, and ngl, every single one of them ate:

• reg_onoff_cnfg2 — the ONOFF_CNFG2 register offset. That's it, that's the whole vibe. 📍
• reg_cnfg_glbl2 — the CNFG_GLBL2 register offset. Like a GPS coordinate but for registers. 🦋
• reg_cnfg_glbl3 — the CNFG_GLBL3 register offset. Third one, still slaying. ✨
• wdtc_mask — the WDTC bit mask in CNFG_GLBL3 (= the bits you update to ping the watchdog). Basically the "hey bestie, you still alive?" mask. 👀 The parenthetical is verbatim, so like, memorize it.
• bit_wd_rst_wk — the WD_RST_WK bit offset within ONOFF_CNFG2. A bit offset, not a bit mask, don't mix them up, iykyk. 🔥
• cnfg_glbl2_cfg_bits — the configuration bits you enable in the CNFG_GLBL2 register. Turn-ons, but make it hardware. 🌈

If you want the full lore, the receipts live here:

• Kernel file ./drivers/watchdog/max77620_wdt.c

That's the one. Go read it. It's giving "the source of truth." 💖

Lowkey a reminder: this page is literally just describing the struct fields, so don't go inventing extra behavior in your head, bestie. The fields mean what they say and nothing more. 💀
